What is TM-30-15 (TM-30-18), and should I use it?

by UPRtek | 2023/01/18

TM-30-15 is a color rendering index system published by IES (Illuminating Engineering Society). A color rendering index system indicates how well a light, when shining on objects, can reproduce the object’s color accurately (compared to a black body radiator – e.g., the sun). TM-30-15 is next in a line of predecessor CRI systems (CIE CRI, GAI, CQS), each intended to improve on previous designs. In this article, we explain TM-30-15, its advantages, and why it’s important.

Automated LED Calibration for Cinema-Stage Light Manufacturing

by UPRtek | 2022/02/09

Cinema LED light manufacturers use what are called “ratio tables” to calibrate their LED lights. This mostly manual process is time consuming, tedious and prone to errors. In this article we will introduce automated LED calibration as a way to speed up calibration many times over and ensure precision color accuracy according to CIE 1931 standards.

What is the difference between a Colorimeter and Spectrometer?

by UPRtek | 2021/11/18

What is the difference between a Colorimeter and Spectrometer? Both devices capture light in order to analyze it’s properties for any number of applications. However, there are some major differences that set them apart. In this article, we will explain the differences by contrasting structural design, functionality, applications, accuracy, advantages and disadvantages.

What is CRI (Color Rendering Index)?

by UPRtek | 2021/06/09

What is CRI (Color Rendering Index)? It is a metric used to measure the ability of a light to bring out colors in objects (i.e. Color Rendering). Lights with a high CRI rating can make store products look brilliant and vibrant. Other lights with low CRI ratings will make the same products drab and lifeless.

What is TLCI, SSI and TLMF?

by UPRtek | 2021/03/02

What is TLCI, SSI and TLMF? They are three metrics used in cinematography to measure a light’s ability to bring out colors (color rendering).

What is Phytochrome Photostationary State (PSS)?
